TUTORIAL DESCRIPTIONS Monday 7 July 1997, 9:30AM--6:30PM

Machine Learning of Natural Language, 9:30AM--1:00PM

David Powers, The Flinders University of South Australia

Over the last 30 years, issues relating to how language can be learned have shaped fields as diverse as linguistics, automata theory, and psycholinguistics. More recently, machine learning and neural nets have found linguistic problems a natural target for exploration and demonstration of techniques. Conversely, computational linguistics, natural language processing and speech technology are all actively looking for ways in which learning can be put to practical use in specific applications. Indeed, the increasing availability of large corpora and treebanks promises that the recent explosion in interest will continue.

This tutorial will provide the participant with an understanding of the perspectives on language learning adopted by the different fields, will explore the nature and significance of the various theoretical results, and will characterize and explain the basic machine learning paradigms and algorithms which have been used for language learning. Recent work will be characterized in terms of this framework, with more detailed case studies being drawn from two different paradigms. The focus here will be on developing an intuition as to how and why the various techniques work.

David Powers is co-author of the Springer monograph 'Machine Learning of Natural Language' and is currently President of SIGNLL, the ACL Special Interest Group on Natural Language Learning. This tutorial will provide background useful to those contemplating attending SIGNLL's two day CoNLL workshop.

Information Retrieval from a Linguist's Perspective, 9:30AM--1:00PM

Sebastian Goeser, IBM Germany Ltd. Gerda Ruge, Technical University of Munich

Information Retrieval (IR) is a dynamically growing field of research and development activities which offers many substantial job opportunities to linguists. The purpose of this tutorial is to introduce computational or theoretical linguists to IR, thus enabling them to make reasonable decisions on linguistic issues in an IR context. The tutorial will give an overview of all major issues in IR research and development that are relevant to a linguist in that context.

An important focus will be the effectiveness of linguistic approaches to IR: Which methods are provably effective, and which ones, in spite of arguments to the contrary, are not? The literature on linguistic IR experiments reports many conflicting results. The IR community is split into those who believe language technology can improve retrieval results and those who do not. The entire IR machinery necessary to understand this situation, in terms of retrieval models, evaluation, system architectures, applications, linguistic representation etc. will be focused in this tutorial.

MAXIMUM ENTROPY MODELING FOR NATURAL LANGUAGE, 3:00PM--6:30PM

Eric Sven Ristad, Princeton University

The maximum entropy framework is a powerful method for building statistical models of natural language. It is expressive, allowing modelers to easily represent their special insights into the data generating machinery. It is statistically efficient, because it models the intersection of complex events without increasing the number of parameters or fragmenting the training data. And it provides strong models, models that can outperform their traditional variants with less tweaking.

This tutorial explains how to build maximum entropy models for natural language applications such as information retrieval and speech recognition. We review the maximum entropy framework, explore the art of effective feature design, and show how to implement models using the instructor's publicly available Maximum Entropy Modeling Toolkit.

Logical Approaches to Syntactic Theories, 3:00PM--6:30PM

James Rogers, University of Central Florida Thomas Cornell, SFB 340, University of Tuebingen

The trend, over the last ten or fifteen years, has been towards specifying syntactic structures in terms of constraints on their form rather than via mechanisms for generating them. This leads naturally to a fully declarative approach in which sets of syntactic structures are treated as sets of ordinary mathematical models and theories of syntax are defined by systems of logical axioms. This model-theoretic approach allows existing tools of mathematical logic to be applied to formal issues in syntax. In addition to the obvious applications to questions of consistency and independence of sets of constraints, results have been obtained establishing the complexity of constraint based theories, logical axiomatizations have been employed as a common framework in which to compare strongly dissimilar generative systems, and automata-based proof techniques have begun to be explored as novel approaches to processing languages axiomatized in this way. This tutorial will explore the foundations of this approach, the results it has yielded so far, and the potential it holds.

The presentation will presume only a passing familiarity with basic formal logic and traditional theories of syntax (e.g., GB and GPSG).

*************************************************************************** POST-CONFERENCE WORKSHOPS

Natural Language Processing for Communication Aids Organisers: Ann Copestake (Stanford University), Stefan Langer (University of Dundee), and Sira E. Palazuelos-Cagigas (Universidad Politecnica de Madrid). July 11 or 12, 1997 The aim of this workshop is to provide a forum in which researchers in communication aids for people with disabilities can discuss the problems involved in these applications and the solutions being investigated in current research. Researchers who are not currently working in this area but who are interested in practical uses for NLP techniques are also encouraged to participate. Applications which we expect to be covered include communication devices for non-speakers, systems designed for deaf users and tools for tutoring and rehabilitation for people with language impairments. Those interested in attending should contact Ann Copestake (aaccsli.stanford.edu). For further details of the workshop see http://www-csli.stanford.edu/~aac/clworkshop.html.

SIGPHON: Computational Phonology Organizers: July 11 or 12, 1997

Concept to Speech Generation Systems Organisers: Kai Alter and Hannes Pirker (Austrian Research Inst. for AI) and Wolfgang Finkler (German Research Center for AI). Friday, July 11, 1997

This workshop deals with Concept-to-Speech (CTS) generation systems, i. e., the production of synthetic speech on the basis of semantic, discourse, phonological and phonetic knowledge. It will thus provide a forum to bring together researchers from the fields of natural language generation and speech synthesis. The aim of the workshop is to stimulate interchange of innovative ideas and results of diverse aspects of CTS generaation and should be especially attractive for people who are interested in language generation and prosody. More detailed information including the program can be retrieved at http://www.dfki.uni-sb.de/~finkler/acl97-cts/index.html. The organising committee can be contacted at cts-7ai.univie.ac.at.

Spoken Language Translation Organisers: Steven Krauwer (Utrecht University; ELSNET, chair), Harold Somers (UMIST; Machine Translation), Doug Arnold (University of Essex), Walter Kasper (DFKI Saarbruecken), Manny Rayner (SRI Cambridge). July 11, 1997

The workshop will be dedicated to spoken language translation (SLT), and its interrelationships with machine translation of written language (MT). It will be a one-day workshop, with four consecutive sessions, addressing the following four issues: current trends in SLT research (approaches, problems); current trends in SLT applications (products, niches); how / where can MT and SLT learn from each other; what can be done to improve convergence or synergy. Contact: steven.krauwerlet.ruu.nl. Details: http://www.cs.columbia.edu/~radev/acl/ACL97/spoken-trans.html.

Envgram Computational Environments for Grammar Development and Linguistic Engineering Organizers: Dominique Estival (University of Melbourne, Australia), Alberto Labelli (IRST), Klays Netter (DFKI), and Fabio Pianesi (IRST) July 11 or 12, 1997

With a growing number of NLP applications going beyond the status of simple research systems, there is also an evident need for better methods, tools and environments to support the development and reuse of large scale linguistic resources and efficient processors. However, while current platforms and components typically provide fairly clean formalisms, processing components and data, it is not yet clear to which extent current results and approaches fit the requirements for scale development and deployment of real NLP applications. Among the relevant issues, we mention: the assessment of the state of the art grammar development and to the division of labor in large scale grammar development; the problems of the reusablility (of linguistic resources and / or processors) and of the usability (from the point of view of the user of the platform). This workshop intends to provide a forum for discussing these and related, crucial issues for Linguistic Engineering.

Operational Factors in Practical, Robust Anaphora Resolution for Unrestricted Texts Organisers: Ruslan Mitkob (University of Wolverhampton, UK, e-mail: R.Mitkovwlv.ac.uk) and Branimir Boguraev (Apple Computer, Inc. Cupertino, CA, USA). July 11, 1997

The workshop will have a dual focus: it will promote the latest trends towards robust, parser-free, corpus-driven and / or other practical approaches to resolving anaphora in unrestricted texts; it will also seek to investigate the role of, and interactions among, the various factors in anaphora resolution and in particular those that scale well in knowledge-poor environments.

Interactive Spoken Dialogue Systems: Bringing Speech and NLP Together in Real Applications Organisers: Julia Hirschberg, Candace Kamm, and Marilyn Walker (ATT Labs Research). July 11 and 12, 1997

Recent advances in speech technologies, natural language processing, and dialogue modeling have made it possible to build dialogue agents for a wide range of applications from voice dialing to accessing information about the weather, train schedules, cultural events or local restaurants. However, there is little research on the integration of component technologies required for these agents. This two-day workshop will address the challenges involved in this integration, including the special requirements dialogue places on speech recognizers, speech synthesizers and natural language generation; tools for building integrated systems; and evaluation of spoken dialogue systems. The workshop will begin with a morning of tutorials on ASR, TTS, and dialogue modeling. We solicit participation from text-to-speech, ASR, NLP, generation and dialogue modeling researchers, as well as those already building integrated spoken dialogue systems.

Referring Phenomena in a Multimedia Discourse and Their Computational Treatment (SIGMEDIA) Organisers: Elisabeth Andre (DFKI, Germany), Laurent Romary (CRIN-CNRS & INRIA Lorraine, France), and Thomas Rist (DFKI, Germany) Organized by the ACL Special Interest Group on Multimedia Language Processing (SIGMEDIA) July 11th/12th 1997

A growing number of research projects has started to investigate the use of referring expressions in multimedia systems. On the one hand, the use of multiple media has led to new problems, such as a proper treatment of cross-media references. On the other hand, it has turned out that many concepts already known from natural language processing, such as cohesion, take on an extended meaning in multimedia discourse. As theories of NL reference become more sophisticated, it is quite natural to investigate whether these theories also encompass other media, such as graphics and pointing gestures. The workshop will be centered around questions, such as "To what extent can linguistic models be applied to multimedia references?", "Which linguistic phenomena can also be observed in multimedia discourse?" and "Is a cross-modality theory of reference possible?". Topics of interest include, but are by no means restricted to the following:

- computational models for the analysis/generation of referring expressions in a multimedia discourse - coordination/synchronization of multiple media, such as speech and pointing gestures - deixis in multimedia environments - cohesion and coherence in multimedia discourse - representation of multimedia discourse - encoding theories for text and graphics - formal models of multimedia referring - referring expressions in augmented/virtual realities - empirical studies

Intelligent Scalable Text Summarization Organisers: Udo Hahn (University of Freiburg), Julian Kupiec (Xerox PARC), Inderjeet Mani (MITRE, co-chair), Mark Maybury (MITRE, co-chair), Kathy McKeown (Columbia University), Boyan Onyshkevych (US Department of Defense), Dragomir Radev (Columbia University), Lisa Rau (SRA International), and Kazuo Tanaka (NTT Human Interface Laboratories). Friday, July 11, 1997

With the explosion in the quantity of on-line information in recent years, demand for text summarization technology appears to be growing. Commercial companies are increasingly starting to offer text summarization capabilities, often bundled with information retrieval tools. These recent developments offer opportunities as well as substantial challenges for research in text summarization. In general, such developments create a practical need for summarization systems which scale up when applied to large volumes of unrestricted text. This workshop is aimed at researchers interested in advancing the scientific frontiers of text summarization to meet these new practical challenges and opportunities. For further information, see http://www.cs.columbia.edu/~radev/ists97.

Automatic Information Extraction and Building of Lexical Semantic Resources for NLP Applications Organized by EuroWordNet (LE2 4003), Sparkle (LE1 2111) and Ecran Organisers: Piek Vossen (University of Amsterdam), Nicoletta Calzolari (Instituto de Linguistica Computazionale del CNR, Pisa), Yorick Wilks (University of Sheffield), Geert Adriaens (Novell Linguistic Development, Antwerp), and Horacio Rodriquez (Politecnica de Catalunya, Barcelona). Friday, July 11, 1997

In the past years the development of high-quality and overall language resources has been the focus of many research groups. More recently also the corpus-based extraction of such resources has gained a wider interest. EuroWordNet, Sparkle and Ecran try to package some of this know-how and expertise into state-of-the-art tools and resources that can directly be applied in NLP-based services. This objective is carried out through the development of software tools in the areas of shallow parsing and lexical acquisition. These tools are used to induce linguistic knowledge from text corpora and are progressively enriched by the information acquired. In this workshop we want to discuss the scope and formats of semantic resources and information acquisition tools with scholars in the field and researchers from commercial R departments who have experience in developing and using them. Specifically we will discuss the following topics: 1. compatibility and standards of multilingual semantic resources and lexical acquisition tools; 2. the validation of multilingual semantic resources and lexical acquisition tools; 3. performances of semantic resources and lexical acquisition tools in NLP tasks; 4. partial or phrasal parsing of text; 5. linking text with lexical databases: sense-differentiation, sense-tagging and sense-disambiguation tasks, domain-differentiation of text and lexical resources. Further details can be found at the Workshop HomePage: http://www.let.uva.nl/~ewn/workshop.htm.

From Research to Commercial Applications: Making NLP Technology Work in Practice Organisers: Jill Burstein (Educational Testing Service), Claudia Leacock (Princeton University), Jared Bernstein (Ordinate Corporation), Andrew Golding (Mitsubishi Electric), Mary Dee Harris (Language Technology, Inc.), Kevin Knight (USC / ISI), Karen Kukich (Bellcore), Lisa Rau (SRA International), Yael Ravin (IBM, T. J. Watson Research Center) Susanne Wolff (Educational Testing Service), and Wlodek Zadrozny (IBM, T. J. Watson Research Center). JUly 11 or 12, 1997

Success in the marketplace is one form of validation for NLP techniques and underlying theories. The broad vision of this workshop is to bring together researchers to discuss commercial or commercial-bound systems that use NLP for either text or speech. We are interested in learning about systems that show promise in re-using NLP techniques, and in the process of technology transfer for NLP applications. Another topic of interest in this workshop is industry-based practical considerations involving NLP technology. The workshop should invoke discussion about experiences and problems -- technical, logistic, or cultural -- among people working on operational and commercial NLP applications. The workshop will begin a dialogue among researchers to explore issues in technology transfer and the re-use of domain-specific systems. Discussion of the issues above would help to create connections between both academic and industry-based research efforts to build a solid infrastructure for NLP technology re-use and lead to a deeper understanding of commercial NLP potential.

Computational Natural Language Learning (CoNLL '97) Organisers: Mark Ellison (Edinburgh University), David Powers (Flinders University), and Walter Daelemans (KUB Tilburg, Antwerp University) July 11 or 12, 1997

The field of computational natural language learning (NLL) is not a new one; research in it has been pursued for more than forty years. The last seven years, however, have seen a growth in interest and, correspondingly, in meetings addressing this topic. These have been held under the auspices of: COLING (The Unfinished Language, 90), DARPA (90/91), AAAI (MLNLO/CNLP, 91/93), IJCAI (NLL, 91), ECML (Machine Learning and Text Analysis, 93), the European Networks of Excellence ELSNET and MLNET (MLNLS, 94), and ESSLLI (96). This year, however, is the first time the that the ACL's special interest group in natural language learning have organised a meeting in conjunction with an (E)ACL conference. This as an important event for researchers in NLL for two reasons. The meeting will provide a venue to share work on our common interests within the NLL community. Secondly, it provides the opportunity for the wider ACL community to become acquainted with NLL work.

For these reasons, we are soliciting for papers from the full breadth of NLL research. This includes work aimed at using machines to learn linguistic models, building computational models of language, and natural language tool development and adaptation. Our coverage explicitly extends to work using probabilistic, symbolic and neural network learning methods, and to the computational modelling of language acquisition. We make no restrictions on the target of acquisition, including work on all levels of language from semantics and pragmatics, through syntax and the lexicon to phonology and phonetics. All submissions will be subjected to blind refereeing by appropriate experts. The combination of this vibrant field, with the occasion of joint EACL/ACL meeting will make this workshop an exciting and stimulating event.

SPONSORS: The organizers are most grateful to the European Commission, the UNED (Universidad Nacional de Educacion a Distancia), the Autonoma University, the Complutense University and the Politecnica University of Madrid for the generous grants they have made to support the conference.

SMOKING POLICY: In Spain, in spite of a decrease in the number of smokers, there are still a lot of people who smoke. Smoking is not permitted in any room at the university but tolerated in other designated public areas.

RECREATION: A variety of athletic facilities (with moderate fees) are available on campus including a summer swimming pool. Athletic passes will be available at the Registration desk.

GEOGRAPHIC SITUATION AND CLIMATE: Located in the center of the Iberian Peninsula, Madrid is 600 m. above sea level. In mid July it is hot but dry, the maximum can vary from 30 to 38 centigrade degrees. Short summer storms in the evening are quite possible.

SIGHTSEEING: The capital of Spain, Madrid is filled with museums, beautiful architecture, fascinating history and charming people that welcome strangers with genuine zeal. From the streets packed with bustling people, to the quiet dignity of a city that is over four-hundred years old, Madrid has much to offer anyone who visits it.

Its forcefulness and personality turn Madrid into an unforgettable city, and its plentiful resources of interest to tourism - nature, art, history - are rounded off extraordinarily well by a series of cities in its surroundings which are full of sights of historic interest, some of which have been included by the UNESCO in the list of places considered "world heritage": Avila, Segovia, Toledo, as well as the Monastery of El Escorial. All of them lie within about 100 km. from the square La Puerta del Sol.

Nearby the conference site is the American Museum were you can enjoy a large collection of Central and South American objects belonging to a variety of cultures. The Museum is within the campus Ciudad Universitaria located at the intersection between the Avenida Arco de la Victoria and the Avenida de los Reyes Catolicos. On the way from hotels to the university, The Church of San Antonio de la Florida, which was declared a National Monument in 1905, was built between 1792 and 1798, and Francisco de Goya's frescoes are a tourist attraction in their own right.

Suitable attire is required for visiting churches.

DIRECTIONS: All air trafic passes through Barajas airport, 15 km. from Madrid. To reach the city either you take the bus or a taxi because there is no metro or fast train. Taxi rates and surcharges: Authorized taxis are white with a red diagonal band on the door. Within the city, and including the airport, the fare is the one indicated on the meter, plus the authorized surcharges. Initial fare: 170 ptas., airport surcharge: 350 ptas., surcharge for night service (11:00pm-6:00am): 150 ptas., for each suitcase: 50 ptas. An aproximate charge in normal traffic conditions from the airport to Plaza de Espana would be between 2500 and 3000 ptas. If you have any complaint, you can ask for a receipt but make sure it's got the taxi's licence on it and the route taken. By bus: There is a yellow bus at the airport wich leaves every 15 minutes and costs 370 pesetas. They do not accept big notes, so change in the airport before taking the bus. The bus takes you to the terminal, in the city center (Plaza de Colon/Columbus square) from where you can take the metro.

By car: Using a car in Madrid is not advisable because there is heavy traffic and it is very difficult to park in the center of Madrid. LOCAL DIRECTIONS: (From the hotels to the conference site): From the hotels: Catch bus 46 at a bus stop in front of the conference hotels (direction Moncloa) and it will take you straight to UNED in "Senda del Rey" (conference site). This bus runs from 6:30am to 11:00pm. A single ticket costs 130 ptas and you can pay on the bus, but we recommend you get a bono-bus (10 trips) which costs 660 pesetas. This is sold at "estancos" (tobacconists) and newspapers kiosks. If you are lodging in the campus residence - Colegio Mayor Antonio de Nebrija- just walk down the Avenida de Seneca and you'll get to the conference site. There will be signs around the campus to help you find your way.

PARKING: Two of the three hotels have parking for a fee but as stated above it is not advisable to drive in Madrid.

FOREIGN CURRENCY EXCHANGE: All bank branch offices offer foreign currency exchange services, and although a considerable number of hotels and many travel agencies do also, it's wiser to exchange your money at a bank office. All banks are open from 8:30 to 2:00, 2:30 from Monday to Friday. If you arrive on a Sunday there is a bank office open at the airport of Barajas. Most hotels and restaurants and many commercial establishments also accept the most popular international credit cards and travellers cheques.
